Claims (9)

A device for banding / looping the material to be packed by a packing band (44) with a protective film (44c),
A coupling / sealing device for coupling / sealing the overlap of the two band layers (44a, 44b) in the loop of the packing band to each other;
The sealing device is used to pierce a packing band protection layer (44c) in at least two electrode members (35a, 35b; 36a, 36b) connected to a power source and one of the band layers (44a, 44b). An apparatus that is a resistance welder including at least one perforated portion. The banding device according to claim 1, further comprising: a second electrode having a perforated portion capable of perforating the protective layer of the second band layer as a tip. 2. The band according to claim 1, wherein the two electrode members of the device are configured so that the tips of the electrode members are electrically connected to each other even when the two band layers are electrically insulated from each other. Hanging device. The banding device according to any one of claims 1 to 3, wherein one or a plurality of the electrode members can be electrically connected to the packing band (44d). Any one of claims 1-4, wherein two clamping elements (38a, 38b; 39a, 39b) of one or more band clamps (38, 39) are used as the first clamping element and the second clamping element. The strapping device according to item 1. Banding device according to any one of the preceding claims, wherein at least one electrode member (35a, 35b; 36a, 36b) comprises a cooling system, in particular a water cooling system. The banding device according to claim 1 or any one of claims 1 to 6,
A banding head for forming a band loop around the packing using a metal packing band and further sealing two overlapping band layers together;
A banding device in which at least one part of a resistance welder is configured in the banding head (5), particularly in the vicinity of the electrode members (35a, 35b; 36a, 36b). The banding device according to claim 7, wherein at least one thyristor device, a connection unit that connects the thyristor device to a power source, and one transformer are disposed on the banding head. A band with a film for loop-tightening the material to be packed, wherein a protective layer is provided on at least one side of the packing band, the packing band forms a loop, and two band layers weigh in part of the loop. Bands characterized in that they are sealed and sealed to one another, said seals taking the form of an electric weld joint, in particular a spot weld joint.
